This invention relates to improvements in card punching apparatus, and particularly toxequipment intended for edge notching cards or sheets.

Among the objects-of the invention, it is proposed to provide a card notching apparatus comprising a card support, a pluralityof groups of punches movable relative to the support, electromagnetic means sequentially activating the groups of punches, and'driving means-for imparting notching movement to selected punches of the sequentially activated groups. The individual punches of a group arelikewise preferably selected electromagnetically, and indicating means associated with the selecting means serves to identify a selected group of punches. The invention also contemplates electromagnetic means for resetting the initial operating sequence of the groups of punches, and in conjunction with the electromagnetic selecting means for the punches, there may be provided switching means common to all of the selecting means.

It is contemplated that certain of the punches have a variable stroke, the extent of which may be determined by electromagnetic means, which means may assume the form of a plurality of electromagnets jointly controlling the stroke. The stroke variation may be effected through a punch actuating member having an adjustable stop, electromagnetic means for adjusting the position of the stop, and driving means cooperating with the actuating member for imparting notching movement to thepunch.

The device of the presentinvention contemplates a keyboard having a plurality of punch selecting keys exceeding the number of punches in a group. According to one embodiment, each group contains three punches for producing notch patterns indicative of values ranging from 1 to 9 in unit increments; and an associated keyboard containing nine numeral keys representing values of from 1 to 9 permits selection of a desired pattern of these punches; a circuit controlling switch is operated by each of the keys; electromagnetic selector means for the punches is arranged in circuit with the switches to produce a punch pattern peculiar to each key; and

driving means is provided to impart notching movement to the key-selected punches.

A plurality of such groups of punches will be sequentially activated by connecting the key controlled switches with one group after another. Accordingly, the invention includes key operated means for interconnecting the switches with the difierent groups of punches. -The elec- 21 Claims. (Cl. 164-113).

tromagnetic punch selectors for each group are sequentially arranged in circuit with the switches to produce a desired punch pattern at each card position, whereupon the notching movement is imparted to the group of selected punches prior to the activation of a succeeding group. The punch group selecting means may respond to the operation of each key on the keyboard. Upon depression of the numeral keys, the switches will close the proper electromagnetic circuits to produce the desired punch pattern, and upon release of the keys, a new group of selecting electromagnets will be included in circuit with the switches. In addition to the numeral keys, the keyboard provides a group selecting key and a reset key, each of which also operates a circuit controlling switch, and'these switches are likewise connected to operate the punch group selecting means.

After a card hasv been properly positioned on the. diev plate of the present apparatus, it is unnecessary to shift the, card with respect to its support untilall desired notching has been accomplished, since agroup of punches is provided for each position on the card, and it will-be notedthat afterthe desired key has been depressed for a particular position on the card, any notching for that position will be completed before selection of the patternior a'succeeding position.

Further objectives of this invention willv become evident from a more detailed-;,d e scription based upon the accompanying drawings wherein: Fig. 1 is a perspective of an encased machine embodying the presentinvention; Fig. 2 is a plan view of the die plate and punch subassembly-of the machine shown in Fig.1;

The machine'show'n in Fig. l is provided with a cover 20 having slots 22 inat least one of its side wallsfor the-introduction and removal of cards to be notchedz -A card to be punched is supported on an inclined die plate 24 whose four edges are notched at 26 to complement punches 42, 44 and 46, pivotally supported thereabove to produce desired patterns of notches at the various card positions. Each group of three punches is providedlwithp signal lamp 2'! arranged behind its respective window 28. A forwardly extending keyboard 30 is provided with numeral;

The various actuators are interposed in the path of one or the'o'throf ithe driving carris 19' 44, when the armatures 1M5 ,Qi; their respective e omasn sare prqieqtedie eir.actuatcrslare movedinto' the path'of one of the driving cams and the corresponding punches are depressed to notch a card resting on the die plate. When the punch is to be operated to notch to the perforation 4, its actuator 65 will be advanced into theipath of the driving cam "I0 by projecting the armature of the electromagnet I02, at which time the adjustable stop 68 will be in its,lower' most position. Where a longer stroke is to be imparted to the punch 46, the electromagnet I04 will likewise be energized, whereupon its armature I06 will be retracted to adjust the adjustable stop 68' to its elevated position. The upper end of the armature I06 of each electromagnet I04 is pivotally connected to a link I00 whose remote end is related in pin and'slot connection with a link III) which depends from a pivot II2 relatingit's upper end with the die plate 24, the lower endof the link I I0 acting to align the toggle links 00 and 02 and thereby raise the adjustable stop to its uppermost position. A spring II 3 carried by'the link I08 between the armature I06 and link I I0, urges the armature and link system to its'original position upon'deenergization of the magnet I04. Inasmuch as the electromagnet IM serves only to change the stroke of the punch, it will be clear that the electromagnets I02 and I04 will be energized jointly where the punch 46 is to receive its increased stroke.

The operation of the system will be best understood by reference to the circuit diagram of Fig. 9. The system is connected with a source of electrical energy by means of a plug II4 supplying conductors II 6 and H8 to which the terminals of the motor I8 are connected and to which a transformer, voltage regulator, or the like, I20 has its input connected. The output of the device I20 is connected with supply leads I22 and I24 which have been identified in'the diagram for purposes of explanation as negative and positive leads respectively, without intending to limit operation of v the apparatus to direct current. Each of the numeral keys 32, as well as the Zero key: 34 and the return key 36, operates a switch whose central arms are connected with the lead I22. The lead I22 is also connected with the intermediate wiper I26 of one bank of contacts of a stepping switch, generally identified by reference character I28. The lead I22 is also connected to a terminal I30 for selective connection with a second bank of contacts I32 of the stepping switch I28, through a switch arm I34 operated with the armature of a slow release relay I36. The contacts I32 cooperate with a wiper I38 which is connected through a lead I40 and theterminals of a magnetically controlled switch I4 2,with one side of the winding of the stepping magnet I44 and with a back contact of each of the key operated switches. The other end of the winding of electromagnet I44 is connected withthe lead I24, and this lead is also connected with one side of the winding of the slow release relay I36 and with a lead I46 common to the lamps 21 located behind the windows 28 which serve to indicate which group of punches is respon sive to' the keyboard at a given time. The lead I24 is also connected with a wiper I50 for sequentially engaging the bank of contacts I52 which determine the group of electromagnets under the control oi the operating keys. It will be noted that each of the contacts I52 is connected with a lead which is common to all of the electromagnets f a group, the groups having been identified in this diagram as GI, G2, G3, G4 and G5. The return leads or the punch selecting electromagnets of theseveral groups having a given value are connected together, and through a 'terminalboard I54, to the key controlled lead of correspondingvalue; which leads are identified as LI, *L2,"L4 and LI-respectively. The lead LI is connected with one'of the contacts of each switchwhose'key is intended to cause the operation' of the '1 punch, thus including the switches of key 1, key 3, key 5 and key 8. The lead" L2, in a similarway, is connected with a contact of each switch whose key is intended to cause the operation of the 2 punch, thus including'the switch of each of key 2, key3, key 6 and key 9.

The lead L4 is connected with a contact of each switch whose key calls for the operation of the"4'punch, which includes key 4, key 5 and key '6, as well as key 7, key 8 and key 9, since it will be remembered that for notching values exceeding six the punch 40 responds to the joint operation of electromagnets I02 and I04. The lead L7 is connected with contacts of the switches under the control of each of key 7, key 8 and key 9.

One of the contacts of the switch controlled by the return key 36, marked R, is connected by means of a lead I56 with one end of the winding of the slow release relay I36.

The armature I58 of the electromagnet I44 cooperates with a ratchet wheel I60 for stepping the several wipers I26, I38 and I50 into sequential engagement with the contacts of their respective banks, the actual advancing movement being imparted by means of a spring as is customary in many commercially available stepping switches, sothat the movement will occur upon release of one of the keys on the keyboard and thereby avoid such unintentional notching as might otherwise result from depressing the key for'too long a period. The armature I58 also actuates the switch I42 which cooperates with the slow release relay I36 following depression of the R key for automatically stepping the switch I28 to itshome position.

With the wipers in their initial positions as depicted in Fig. 9, and with a card positioned on the die plate of the machine, the operations might proceed as follows:

Assuming that the first position of the card is to be notched with the value 1, key 1 will bedepressed, making the circuit of magnet I of group 1 through the wiper I50 and its first contact I52;.and, indicating lamp 2! for group one will be energized through the wiper I26 and the first of its contacts I21. As long as the key 1 is held depressed, there will be no stepping of the switch I28; when the key is released however, the wipers for the various banks of contacts will be stepped one notch to the second position at which they energize the second group of punches and the second indicating lamp respectively. Following the selection of a particular punch or combination thereof by depression of a key, it will be recalled that the continuously rotating driving cams 10 will engage the actuator stops for the punches selected and notch the card accordingly. In the event that a zero value is to be indicated at any position of the card, the zero key 34 will be depressed, the closure of whose switch results onlyin a stepping impulse through the electromagnet I44 without causing a notch ing operation at this position of the card involved. After the notching operations for a given card hays been completed, the initial sequence can be restored by merelyd'epressing and releasing the f theaother v keys, oper el c mm it of e, wiper I38 is inengagementfwith any of its contacts; I32 eirceptlth 'ffrrst o e, sinceltherelay l3 6.-is de s j fied .f r slowgel' as tc, mai ta nin Twinn n i313 and i 34 ,inengagement for a prolongedperibd, it l le'w' fl h tgmaent L 'w l lbe e eat r ig dami i-i h r; h ugh-the w c I42 3 h lw se stn ingsw tch r s ns h i ti Ps itiQn -r A thi time a e i- P w es up t guts; o tacts I32 which'is not"'connected"with the 0th The foregoing description will suggest inodi tiw etq th e ill the art Ju t-a t e nt mssli as.
